Given m||n, find the value of x.<br> 135
Viefleur [7K]

Answer: Option C.

Step-by-step explanation:

Let as consider the complete question is same as question shown in the below figure.

In the figure m║n.

If a transversal line intersect two parallel lines then same sided interior angles are supplementary angles and their sum is 180 degrees.

3x+x=180^{\circ}

4x=180^{\circ}

Divide both sides by 4.

x=\dfrac{180^{\circ}}{4}

x=45^{\circ}

The value of x is 45 degrees.

Therefore, the correct option is C.
